The concentration of zinc in the hair of 219 schoolchildren aged between 10 and 11 years was measured and related to height, weight, estimates of consumption of zinc-rich foods, number of children living at home, and rank in family. None of the correlation coefficients between hair zinc and the other variables was significant. Mean concentration of zinc was higher (P less than 0.001) in the girls (146 microgram/g; 2.23 mumol/g) than in the boys (118 microgram/g; 1.81 mumol/g). Eight children (3.7% of the total) had less than 75 microgram/g (less than 1.15 mumol/g) zinc in their hair but only one of them was below the 10th centile for height or weight--a girl with coeliac disease.
对219名年龄在10至11岁的学童头发中的锌浓度进行了测量，并将其与身高、体重、富含锌食物的摄入量估计值、家中孩子数量以及在家庭中的排行进行关联分析。头发锌含量与其他变量之间的相关系数均无显著意义。女孩头发锌的平均浓度（146微克/克；2.23微摩尔/克）高于男孩（118微克/克；1.81微摩尔/克）（P小于0.001）。8名儿童（占总数的3.7%）头发中的锌含量低于75微克/克（低于1.15微摩尔/克），但其中只有一名儿童的身高或体重低于第10百分位数——一名患有乳糜泻的女孩。
